Cara Membuat Validasi Upload Type File CodeIgniter Part2

Melanjutkan dari sesi sebelumnya dan di kesempatan kali ini saya akan menjelaskan cara merancang validasi upload type file codeigniter part2.Â Namun di penjelasan di sesi sebelumnya teman-teman telah mengerjakan konfigurasi standard CodeIgniter, selain itu teman-teman pun telah merancang satu buah file view dimana dari kode file view tersebut yakni bagi menampilkan layout form upload yang digunakan. Dan di penjelasan ini akan berlanjut merancang satu buah file Controller bagi melengkapinya. Seketika saja bagi membuatnya kalian dapat ikuti tahapan yang saya berikan dibawah ini.

Berikut Tahapannya :

Teman-teman buka folder project CodeIgniter nya.
Masuk kedalam directory folder application/controller , dan bikin satu buah file didalamnya dengan nama Upload.php
Seandainya telah berikutnya ketikan seperti kode berikut :

<?php<br />
defined(‘BASEPATH’) OR exit(‘No direct script access allowed’);</p>
<p>class Upload extends CI_Controller {</p>
<p>	function __construct()<br />
	{<br />
		parent::__construct();<br />
		$this->load->helper(array(‘form’,’file’));<br />
	}</p>
<p>	public function index()<br />
	{<br />
		$this->load->library(‘form_validation’);<br />
		 $this->form_validation->set_rules(‘userimage’, ‘Profile Image’, ‘callback_cek_upload’);<br />
		 if($this->form_validation->run() == TRUE){</p>
<p>		     echo “Success uploads file image..”;</p>
<p>		 }<br />
		 $this->load->view(‘upload’);<br />
	}</p>
<p>	function cek_upload(){<br />
		if($_FILES[‘userimage’][‘size’] != 0){<br />
		$upload_dir = ‘./images/’;<br />
		if (!is_dir($upload_dir)) {<br />
		     mkdir($upload_dir);<br />
		}<br />
		$config[‘upload_path’]   = $upload_dir;<br />
		$config[‘allowed_types’] = ‘gif|jpg|png|jpeg’;<br />
		$config[‘file_name’]     = ‘userimage_’.substr(md5(rand()),0,7);<br />
		$config[‘overwrite’]     = false;<br />
		$config[‘max_size’]  = ‘5120’;</p>
<p>		$this->load->library(‘upload’, $config);<br />
		if (!$this->upload->do_upload(‘userimage’)){<br />
		    $this->form_validation->set_message(‘cek_upload’, $this->upload->display_errors());<br />
		    return false;<br />
		}<br />
		else{<br />
		    $this->upload_data[‘file’] =  $this->upload->data();<br />
		    return true;<br />
		}<br />
		}<br />
		else{<br />
		$this->form_validation->set_message(‘cek_upload’, “No file selected”);<br />
		return false;<br />
	}<br />
	}</p>
<p>}

<?php

defined(‘BASEPATH’) OR exit(‘No direct script access allowed’);

class Upload extends CI_Controller {

function __construct()

{

parent::__construct();

$this–>load–>helper(array(‘form’,‘file’));

}

public function index()

{

$this–>load–>library(‘form_validation’);

$this–>form_validation–>set_rules(‘userimage’, ‘Profile Image’, ‘callback_cek_upload’);

if($this–>form_validation–>run() == TRUE){

echo “Success uploads file image..”;

}

$this–>load–>view(‘upload’);

}

function cek_upload(){

if($_FILES[‘userimage’][‘size’] != 0){

$upload_dir = ‘./images/’;

if (!is_dir($upload_dir)) {

mkdir($upload_dir);

}

$config[‘upload_path’] = $upload_dir;

$config[‘allowed_types’] = ‘gif|jpg|png|jpeg’;

$config[‘file_name’] = ‘userimage_’.substr(md5(rand()),0,7);

$config[‘overwrite’] = false;

$config[‘max_size’] = ‘5120’;

$this–>load–>library(‘upload’, $config);

if (!$this–>upload–>do_upload(‘userimage’)){

$this–>form_validation–>set_message(‘cek_upload’, $this–>upload–>display_errors());

return false;

}

else{

$this–>upload_data[‘file’] = $this–>upload–>data();

return true;

}

else{

$this–>form_validation–>set_message(‘cek_upload’, “No file selected”);

return false;

}

Seandainya telah simpan file tersebut dan lihat hasilnya di browser kesayangan teman-teman.

Hingga disini penjelasan saya mengenai cara merancang validasi upload type file codeigniter part2, semoga bermanfaat.
